Abstract: The subject disclosure relates to detecting lead data representing any one or more of a range of leads and transmitting notification data to a data store based on detection of the lead data. In an example, a computer program product is disclosed that comprises a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to detect first data representing a type of lead, from one or more first data store based on lead criteria data. The computer program product also causes the processor to determine whether a subset of first data matches second data representing existing customer information.
